,'To all whom it may concern:

Be it known that I, HENRY E. SHAFFER, of Rochester, in the county ofMonroe and State of New York, have invented certain new and usefulImprovements in Burners fo" Acetylene Gas; and I dc hereby declare thefollowing to be a full, clear, and exact description .of the saine,reference being had to the ac companying drawings, forming a part ofthis specification, and to the reference-numerals My present inventionhas for its objects to lprovide an improved burner for gas rich incarbon, such as acetylene gas, whereby notonly will the light bcimproved and more perfeet' combustionl had, but the dame will4 be freefrom the fluctuations due to variations in pressure of the gas and tothese and other ends the invention consists in. certain im` provementshereinafter fully described, the novel features being pointed out intheclaims at the 4end of this specificationl In the drawings, Figure l is aside eleva- `tion of a Agas-lnirner constructed in accordance with 'myinvention; Fig. 2, a vertical view'of a modification; Fig. 4, ahorizontal sectional view of the burner shown. in Fig. 3; Fig. ,15,-across-sectionalview on ,the line a: o: of Fig. 2.

Similar reference-n u merals indicate similar i parts.

l .be transmitted to the burner-body, I reduce' In Figs. l and 2 I haveshown the preferred form of burner, consisting generally of a bodyvportieri l, preferably of metai, having a gaspassage f3, a centralchamber Eaand also an upwardly-extending external projection 4,preferably formed with the. burner-body and projecting between andpreferably 'close to the under sides ofzthe flames from two burner-vtips 5, arrangedwith their gas-orifices atan angle to eachother andreceiving gas' from the central chamber 3." The object of the projection4 is'to providea mass of material below the point of cooperation of twogasjets impinging at an angle, which will become heated'by proximitytothe 'flames and will in turn' react np'on the gas and promoteits'combustion and heat the air 'that reaches the- :Ilame from below.'In order that as little of the heat of the projection 4 as possibleshall the supporting portions thereof as much as possible by cuttingaway the metal beneath it, as at 6, leaving only the narrowsupporting-arms 7, which are strong enough to hold the projection, butoder a veryvsnlall heatconducting surface.

The burner-tips 5 are each constructed of soapstone, lava, or similarrefractory material and are preferably provided With two passages 8 and9, the former, constituting the entrance-passage, being in communicationwith theinterior of the chamber 3, and the latter, being thedischarge-passage, extending at an angle to the former and communicat--air-passages, which insures the air entering the passages striking thecolumn of gas at rightangles and when it first issues from the aperturel0. 'I prefer to form the passage 9 by drilling in from the outer end oft e tip. Then lthe minute aperture 10 is drilled, and then the passages1l are formed by passinga larger drill through from side to 'side of thetip, the center of said drillbeing about on a level with the bottom ofthe passage 9, as will be understood from an inspection of Figs. 2 and5.

Near the outerend of the passage 9 are provided verysmall lateralpassages 12, serving to admit air to the column of mixed airand` `gasnear the point of combustion, effectually surrounding it andY preventingContact with the extreme end of the tip, thereby prevent ing undueheating of the latter and the formation of a deposit thereon. Tips. thusconstructed l find give very good results and insure the consumption ofal1 of the gasA without causing the deposits which sometimes impair vtheeiiiciency of burners of this class, and by the arrangement of thepassages vil and 9 at an angle, as shown, thc tips may be readilyemployed not only in the form of burner shown in Figs. 1 and 2 forproducinga flat name,

2 l "swab but. also to produce separate vertical jetsyas shown inFigsf'B and 4, as will be described.

. The burner shown in Figs. 1 and 2 not only is well adapted for use inconnection with the particular form oftip shown, but the feature ofhaving/a central gas-chamber 3 and the gas-,passages tothe tip out ofline with the inletypassages is particularly advantageous, because theflame is relieved from fluctuaio tions due tovariationsin the pressureof the gas, the gas contained inthe chamber -forming a cushion to someextent an'd insuringV a comparatively even supply'to the dame, and.

the angular arrangement of the passages' i5 and 9 in the tip contributesalso to this result. y i

While it is'de`sirable to' have the -buruertips herein shown anddescribed arranged at an angle to produce a flat flame, they Varecapableof use in a humor-body of the forni of that shown in Figs. Baid4, in which the upper portion (indicated by is provided with horizontalradial apertures adapted .to receivethe tips, the passages 9 beingverti- 215 cally arranged to produce a seriesof vertical flames, andwhile I have shown four tips attached any number desired could beemplyed. In this construction also it will b e noted that the interiorof the body constitutes 3o a chamber and the passages in the tips arenot in a direct line with the inlet-passage 21, so that the flickering-of the 'llame due to variations in pressure is materiallyrednced. n Thetips couldV be molded or otherwise formed, if desirable, and thespecific form changed without departing from the spirit of my in venton;but-I 4prefer that the channels Band 9vbe ai angedat an angle, as shown,as l this feature prevents undue flickering by reason of-the change indirection of the dow of gas and also facilitates the application to theforms of burner-bodies shown herein. I

I claim 'as my ifventiony i y l 1. In a bui-nerv for 'acetylene andsimilar gases, the combination with the burner-body having the `taperingextension and the round gas-apertures discharging gas'in convergingstreams above the extension and substan#V tially parallel with the facesthereof, therebyucausing ltheextension to be heated by the Haines.

3. The combination with the `burner-body -irst issues into the passage.

and the burner-tips discharging gas in 'een verging streams above thebody, of the ex tension formed on' the body and arranged be-l tween thetips and having aI narrowr connesa of, tion with the body to preventconduction of, heat to the latter. l
